Title: Method and system for chemical reaction
Inventor: OMI TADAHIRO
IPC: C25D11/32
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To prevent a reaction by-product, i.e., gas molecules, from blocking high speed uniform reaction for forming porous silicon by performing a chemical reaction while controlling the concentration of a gas dissolved into the reaction liquid in a reaction tank below an under reaction saturation solubility. SOLUTION: A silicon wafer 200 is brought, on one side thereof, into contact a reaction liquid 201 and, on the other side thereof, to a conductive solution, i.e., an electrolyte 202. A negative voltage is applied to the reaction liquid 201 through a negative electrode 203 and a positive voltage is applied to the conductive solution 202 through a positive electrode 204. A PID cooler/heater or a heat-exchanger is set on a circulation line 210b in order to heat/cool the circulating reaction liquid. Preferably, the heating/cooling is performed to keep the temperature of the reaction liquid 201 in a reaction tank 30 within ±0.5. When the quantity of hydrogen dissolved into the reaction liquid 201 in the reaction tank 30 is observed under that state, it is about 1 ppb or less which is significantly lower than the saturation solubility, i.e., 1 ppm, during anodic formation.

Title: Packing material prominent in disposal
Inventor: HIRAYAMA MASAHIRO
IPC: B32B7/00
Filed: 1991-05-28
Abstract: PURPOSE:To provide a packing material for packing snack cakes which decomposes when left in nature not to pollute environment and prominent particularly in gas barrier. CONSTITUTION:Decomposable plastic which decomposes in the presence of water, light and microbe or enzyme is mixed with another plastic and made by extruding into film having a thickness of 30 to 120mum. On one side of the film, a thin film layer of aluminum having a thickness of 100 to 1000Angstrom  is formed by vacuum deposition to obtain a packing material. Thus, when the packing material is thrown, a plastic layer is decomposed by water, light and microbe or enzyme and at the same time the thin layer laminated on the plastic layer is atomized and broken, so that the whole packing material is decomposed. As a result, pollution of environment can be prevented.

Title: Fiber composite rain gutter and its manufacture
Inventor: HAYASHI HITOSHI
IPC: E04D13/064
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To make it difficult to produce deformation, breakage, peeling and corrosion by containing a reinforced short fiber, and diffusing a modified polyolefin resin in a polyolefin resin as a matrix, and molding a composite molten phase comprising both the resins into a rain gutter shape. SOLUTION: A fiber composite rain gutter 8 is manufactured with a molding device by using a polyolefin resin 9, a modified polyolefin resin 10a and a reinforced short fiber 10b. Since the reinforced short fiber 10b is diffused in a polyolefin resin matrix through the resin 10a, the resins 10b, 10a are firmly bonded. The linear expansion ratio of the gutter 8 is reduced by firmly binding the resins 10a, 9. In addition, since it is formed of a flammable polyolefin resin, it can be incinerated. Furthermore, since it is integrally manufactured, peeling does not occur. At the time, an amount of filling of the fiber 10b is 2-30 vol.% of a composite molten phase, and the diameter of the fiber 10b is 3-30 cm. Thereby recycling is facilitated and the reduction of a production cost can be contrived.
